Power supply is quietly becoming the real constraint for AI scaling—way more people are sleeping on this than realize. The challenge isn't just flipping a switch. You're dealing with voltage conversion headaches, keeping GPUs from melting under load, managing thermal chaos across massive compute farms. Current bottleneck? Human engineering can only push so far. But once humanoid robots come online, they can tackle the physical infrastructure work that's slowing everything down now. That's when things actually accelerate.
